Using Postgres and PGAdmin -4.

John,
Are you aware of SQLite or DuckDB?
Unlike PostgreSQL, which is an (excellent) client-server RDBMS,
the former two are "embedded" disk-based databases, which are quite capable.
"Deployment" is trivial. And their SQL engine are more sophisticated than most people realize.
Not that I want to turn you away from PostgreSQL, but they do have advantages, FWIW.
Having DBs be a single file on disk easily shared is quite convenient.
The reason I mention it here, is that SQLite for example has tons of ready-made GUIs,
with some of the Windows one being just 1 .exe indeed. Most allow to view the tables
in "Grid UI controls", some allow modifications too. They are not MS Access like, in the
sense that they don't allow writing custom UIs on top of the DB, just view and edit DB
tables. But maybe that's enough for your hobby project?
